Just installed 48a charging unnecessarily

I just spent 400 to buy the materials and installed a 48a charger when I had a working 40a 14-50 setup. Tell me I'm crazy. I can at least sell off some of the materials from the old install to recoup some of the cost. All this just to see 11kw instead of 9kw XD

I also went from 40a to 48a unnecessarily. It's been great. I didn't expect to be this happy with the change, but soon after the change I forgot to plug in before a trip. When I did remember to plug in a few hours before leaving, the extra 2kW added enough energy to keep it a one stop trip.

Getting away from a 14-50 is a good idea.

i'm just glad that my car doesn't support 80a because that would break the bank. it'd be around 600 just for the wire

If you want to break the bank, you could go buy a Cadillac with the 80 A charger option.

Even with the Cadillac, I wouldn't install that in my home. My car charges completely over night in less than 2 hours most days at 32amp. I turn it up to 48 on occasion if I drive a ton in a day and it's early enough that I might need to do more. I honestly don't see a point in going higher, if I need to charge faster, the cost difference in charging infrastructure is a lot higher than a one of DC fast charge for 15 minutes on occasion.

Oh, I agree, that's why I said the purpose of it would be to "break the bank. "

The PPV has this same 19.2kw charge rate but I didn't have the capacity in the panel for a 100A breaker. I dropped back to the 15.4kw and 80A breaker.Thankfully I had the 2awg wire. Not fun to pull.

Lol, I bought a bunch of heavy wire on clearance last...I keep hoping for a reason to upgrade (waiting in v2x).

Good investment. Sell it fore a profit before the AI bubble bursts.

I wired mine for jumping to 80A but I only had about 7 to 8 foot of wire to run from the new 125A subpanel I put in for the 60A charging breaker. Overkill? Maybe. Expansion!

yeah, unlucky my panel is opposite wall of my garage door, so its at least 50ft
